1. Preheat oven to 200ºC/400ºF.
2. Butter dish or baking sheets with a piece of butter.
3. Cube the cold butter.
4. In a bowl, mix the 4 cups of flower, the baking powder and salt.
5. Add the butter cubes and mix until you get a sandy mix (something similar to pebbles of sugar). See 1st picture. You can use a food processor to avoid the butter to melt.
6. Mix the 4 eggs and the heavy cream together (see 2nd pic). Add to the flour mix.
7. Cut the cheese into little cubes (see 3rd pic).
8. In a bowl, mix the cheese with the dill and the tablespoon of flower (pic 4). This will help them to distribute evenly throughout the dough. Add to the rest of the ingredients.
9. Knead for about a minute until you get a pretty wet dough (pic 5).
10. Divide the dough into little pieces and put in muffin rack (pic 7) or flatten dough using a rolling pin and cut with a knife into pieces (see 6th picture).
11. Beat the remaining egg with a tablespoon of fresh water and brush each scone with it (see pictures 7 and 8).
12. Bake for about 20-25 minutes, or until golden brown (see pictures 9 and 10).
13. Cool scones on a wire rack and serve warm.
14. Enjoy!
